Expecting a baby? Here are some important questions to ask your obstetrician & gynaecologist.

Last updated on 1 November 2021

Once the news of your pregnancy wears off, the euphoria you experience may start to turn into anxiety. Be sure to make an appointment with an obstetrician & gynaecologist to address any concerns you have.

If you’re unsure of what to ask your doctor during your first pre-natal checkup, we’ve got you covered!

Q: What type of pre-natal tests or screenings will I need to do in the coming months?

For the first trimester (at 10 – 12 weeks), your doctor will usually recommend an ultrasound scan and antenatal blood tests. Prenatal testing for Down syndrome is also typically recommended. At 20 weeks of pregnancy, there is usually a detailed fetal anomaly scan on the foetus. Your obstetrician & gynaecologist may also order a glucose screening to test for gestational diabetes at 28 weeks of gestation.

Q: How much weight should I gain in the course of my pregnancy?

First trimester questions - Weight gain
The amount of weight you should gain during pregnancy is based on your body mass index (BMI) before pregnancy.

These are weight gain recommendations if you are pregnant with one baby:

  • BMI less than 18.5: 12.7 – 18.1kg
  • BMI 18.5 – 24.9: 11.3 – 15.9kg
  • BMI 25.0 – 29.9: 6.8 – 11.3kg
  • BMI greater than or equal to 30.0: 5 – 9.1kg

If you are pregnant with twins, follow these recommendations:

  • BMI less than 18.5: 22.7 – 28.1kg
  • BMI 18.5 – 24.9: 16.8 – 24.5kg
  • BMI 25.0 – 29.9: 14.1 – 22.7kg
  • BMI greater than or equal to 30.0: 11.3 – 19.1kg

In general, if you start out at a healthy or normal weight, you should gain about 1 to 1.8 kg during the first trimester and 0.5 kg a week in the second and third trimesters.

If you are expecting twins, you should gain an average of 0.7 kg per week in the second and third trimesters.

Women who have a BMI of 25 and above are recommended to gain about 0.2 kg a week in the second and third trimesters.

Q: Am I genetically predisposed to certain medical conditions that may be considered of high risk to the fetus? If so, what are the preventative measures I can undertake to minimise my risks?

High blood pressure, diabetes and autoimmune diseases such as lupus and multiple sclerosis can increase a woman’s risk for preeclampsia, preterm birth or stillbirth. Discuss with your doctor on viable steps you may take to reduce these prospects.

Q: What are some normal pregnancy symptoms to expect and how can I manage them?

First trimester questions - Symptoms
Usual symptoms include:

  • bloating
  • heartburn
  • fatigue
  • tender breasts
  • fatigue
  • constipation
  • headaches
  • food aversions or cravings
  • mood swings
  • nausea

Your obstetrician & gynaecologist can advise you on signs to watch out for so that you may be better prepared.

Q: What kinds of food should I start eating more of?

Lentils and spinach are considered to be superfoods for pregnant women as they contain more than half of your daily folate requirement in a single serving. They are also rich in potassium, iron, phosphorus, magnesium and vitamins A and B6, necessary nutrients that aid in the growth of fetal tissue and organs. Walnuts, raspberries, wild salmon, kale, lean chicken, sweet potatoes, avocado and chocolate (in small doses) are also recommended. If you’re a vegetarian or a pescatarian, consult your doctor on what best to incorporate in your pregnancy diet.

Q: What should I start eating less of or abstain from eating altogether?

First trimester questions - What to eat less of or avoid
Anything raw is a definite no-no, and this goes for fish, shellfish, eggs and sometimes even vegetables, as trapped mud in some vegetables may be breeding ground for E. coli and salmonella.

Avoid soft cheeses such as brie, gorgonzola, camembert, roquefort, feta or queso as they are made from unpasteurised milk and may contain listeria.

Abstain from alcohol as it may pass through the placenta and into the baby’s blood stream, resulting in fetal alcohol syndrome.

Any fish that registers high mercury levels should also be avoided, such as shark, swordfish, tilefish, canned tuna and king mackerel.

Q: Should I start eating for two?

Overeating can result in excessive weight gain and gestational diabetes, which in turn can put you at risk for pregnancy complications. If you feel hungry often, choose healthier snacks such as blueberries, hummus, yogurt parfait, kale chips or granola mix.


Practise moderation in everything, including sex, exercise, massages (avoid deep-tissue) and hair treatments (opt for highlights or henna if you are concerned about chemicals seeping into the skin and bloodstream). If you are going for a manicure or pedicure, ask for 3-free nail polish if you’re wary of the ‘toxic trio’ of dibutyl phthalate, toluene and formaldehyde.

Feel free to ask your doctor any other questions that are weighing on your mind.
